Well I'll start. These dynos go back to 2009... I think they're same day. Numbers are uncorrected and all runs were on a stock auto transmission, stock placement on the fuel screw on all runs.
First run was stock fuel with an intake and 14cm housing on the stock turbo. 3200spring too I think...
141/379 uncorrected
Next one is same as above plus a dennyt#2 pin
168/512 I think is what it says...
Last one is same as the first 2 plus 55mpl DDP 4 hole injectors.
231/675
I have one more dyno graph in a folder in my desk from after with the same fueling where I had installed an he351. Transmission was getting tired at that point but the power went to 248/5xx. I can't remember the tq number anymore...
fuel screw turned in 1/8 from runaway
timing bumped slightly
denny t 2
3200 gov
stock turbo
custom intake w/ 7 inch s&b filter
4 inch straight pipe
3 inch lift
35s
3.07 gears
Made 253/608 on the second of 3 pulls....blew a radiator hose so no 3rd run...the guy from dp tuner who was running it on the dyno said he there was more left in it he would guess it was prolly 265-270 and 620-630...but for now all we got is 253/608...
hoping with my mods I have (4inch DE. denny t pin. BHAF timing and pump work) ill be somewhere around 400-420, well see towards the middle of summer when I actually get it done
I'm digging the dyno results! I like seeing others' results so i can guesstimate my own. maybe this summer i'll put it on a dyno - we'll see.
I know there are two main types of dyno's... is there one that is better suited for diesels/turbocharged engines? which is more popular? Don't mean to hijack the thread...
I got 5x18 injectors, 63/65/14 turbo, Hamilton 188/220 camshaft, and just a 3" crossover tube(non-ic still). As far as the injection pump goes, the fuel screw is turned in 2 turns, I ground down the factory fuel pin, and the star wheel is raised up all the way, and skipped a tooth on the timing. It has a manual trans with 3.07 gears.
Scheid 14mm VE with KTA head and rotor, arp studs, ported exhaust, 62/65/14 with 360 deg bearing and internal gate, 38mm external gate, 5x25's from Scheid Diesel, NX two stage with .125 solenoids and no jets, 28 deg timing (est), Airdog 165gph, 47rh trans with lockup.
Tom Collins made 587 with a 12mm VE, w/m, and bottle. Cole Dow was over 700 by his dragstrip numbers if you want to count p-pump trucks. Both 518 transmissions, which are basically the same with OD.
Meaning, that could be made on a 727..... no difference, unless one runs on a dyno in o/d. No reason to do that unless the dyno is not loaded properly.
No idea........was I don't know what his efficiency of his converter is. But, I would guarantee that on the right day it would of been over 500 with a manual trans.
My daughter went 12.60s on a original 727 trans. We swapped to a 47rh and a few other things and went 11.68 was her best. All on fuel with water inj only and a stk 12mm pump.
the 426 and 440 were making 450+ with a 727 behind them from the factory, not near the torque of a 400hp cummins, but they are a beast of a transmission
Here is a graph from my '92 from about 10years ago. 609HP 1292tq on fuel only. 14mm VE, HX35/40-HT3B, honed POD's, etc. You can see on the graph that was run #190 - made a few pulls with it over the years! That truck was a blast to drive - super responsive. Wish I have kept it when I bought my new tuck!
